Subnational variations in conceptions.

Conception statistics are derived from information collected at the registration of live births, still births, and legal abortions. This article looks at how conception rates vary across England and Wales using the 1991 ONS area classification of DHAs (Population Trends 79). A comparison is made between age-specific conception rates for different area classification groups in 1993, and changes between 1983 and 1993 are examined. Correlations between certain social and economic factors and conception rates are also analysed.

Variation in fertility between different types of local area.

Trends in fertility at the national level have been described in a recent article in the Population Review series. This article examines variations in the pattern of fertility experienced in different kinds of area within England and Wales. For this purpose use is made of the new ONS classification of local authorities into 11 groups and 29 clusters of areas with similar socio-economic characteristics. The classification was developed from statistics collected in the 1991 Census of Population. Although proportions of residents aged 0-4, 5-14, and 25-44 were among the 37 Census variables used to define groups and clusters of similar areas, the analysis did not make direct use of any measure of fertility related to ages of women at childbirth.

Patterns of infant mortality from Armenian parish records: a study from 10 countries of the diaspora, 1737-1982.

Using parish records from 10 different countries with small Armenian communities, this study compared patterns of infant mortality in these countries over a period of 245 years. Deaths registered as aged < or = 1 year were used to estimate the numerator for the infant mortality rates (IMR) while the denominator was estimated from births in the same year based on baptisms in the appropriate registers. To check on the validity of using the baptisms as the denominator for the IMR, records of infant deaths were linked with the baptismal records. Thus, from a sample of 273 infant deaths 78.4% had a baptismal record in the registers of the same church in which the death was recorded. Of the deaths 60% had a recorded cause of death. Over the past 245 years, IMR have fallen substantially in all parishes. However, there were notable exceptions to this general pattern of declining IMR over time. For example, the IMR was tripled in Palestine during the decade of the First World War, possibly as a result of the influx of refugees deported from Turkey. A study of the seasonal occurrence of the deaths revealed peaking of deaths between May and August, a pattern influenced by the relative importance of gastroenteritis as a cause of death during the summer months in Egypt where the majority of these infant deaths were recorded. A review of the most important causes of death helped identify an outbreak of undetermined cause in Belgrade in 1737 and an outbreak of dysentery deaths in Alexandria, Egypt, in 1909.(ABSTRACT TRUNCATED AT 250 WORDS)

Age at return marriage and timing of first birth in India's Uttar Pradesh and Kerala states.

The study investigates the relationship between age at marriage and the length of first birth interval in two states of India: Uttar Pradesh and Kerala. Life tables of first-birth intervals and median first-birth intervals are computed for several subgroups of the study population. Multivariate hazards modelling technique is used to study the net effect of age at marriage, controlling for a multiple of socioeconomic factors. The result shows that the average first-birth interval varies by age at marriage and is much longer in Uttar Pradesh than in Kerala.

Towards regional equality in family planning: teenage pregnancies and abortions in Finland from 1976 to 1993.

BACKGROUND: A major goal of Finnish family planning policy since the 1970s has been to minimize unintended pregnancies by providing equal contraception and abortion services throughout the country. This report looks at how this policy has succeeded among teenagers. METHODS: The data on childbirths, induced abortions and mean populations were collected from the national abortion and population registers. Regional and age-specific rates were calculated for fertility, abortions and pregnancies in girls aged 15-19. RESULTS: In 1993, the teenage pregnancy rate was 20/1000 and the abortion rate 9.5/1000 in the whole country. Although the pregnancy rate had dropped by half since the 1970s, the regional differences were still there: the lowest rate was 18/1000 and the highest 29/1000 (in Lapland) in 1991-93. The abortion rate ranged from 8/1000 to 14/1000. Childbirths decreased, particularly at the beginning of the study period, while abortions declined sharply towards the end of the period. In 1986-88, the abortion ratio exceeded 100 in all provinces except two. In the 1990s, it dropped below 100 again except in the capital province. In 16-17 year-olds, the trends were quite equal in different provinces. In 18-19 year-olds, pregnancies remained more frequent in the north and were more often carried to term, while the choice of abortion was more likely in the south. CONCLUSIONS: Equally declining trends in pregnancies in all provinces suggest that teenage family planning services have a comprehensive coverage. However, regional differences still remain and imply a detailed analysis of their reasons.

Marital status behaviour of women in the former Soviet Republics.

This paper uses the most recent data and life table analysis to describe the marital behavior of women in the republics of the former USSR. For the first time a multistate life table analysis was used to describe the marital careers of women from all the 15 republics. In the near future, such a comparative analysis will no longer be possible due to the unavailability of statistical data, especially in some of the Asian states. The analysis shows that despite 70 years of influence by Soviet ideology and lifestyle, the institution of marriage was little subject to rapid change, and retained its traditions for each culture and its ethnic features. Marriage was a universal institution in the former USSR. The majority of the women in all of the former republics entered marriage at least once. The mean age at first marriage varies from 20.5 in Moldavia to 22.8 in Azerbaijan. The proportion of marriages that end in divorce differs from 16% in Georgia to 41% in Latvia. On average more than 30% of divorced women remarry in Latvia and Ukraine and less than 5% in Georgia.

[The social geography of AIDS in Brazil].

The first of a series of papers concerning the evaluation of the dynamics of the AIDS epidemic in Brazil employing techniques of geographical analysis, is here presented. Results of research undertaken in the US (especially in New York City) are compared with those of a recent investigation carried out in the city of S.Paulo, Brazil (Grangeiro, 1994). In both, geographical patterns of socio-demographic variables correlate with different patterns of the spread of the AIDS epidemic through the transmission groups. Recent trends of the AIDS epidemic in Brazil: the displacement toward medium sized cities and expansion frontiers, increasing report of AIDS cases among the poor and underprivileged, changes in the pattern of transmission with proportional augmentation of heterosexual transmission and IDUs as transmission groups, are described and analysed. The geographical distribution of the AIDS cases registered between 1987-1993 in Brazil throughout the Brazilian States is evaluated by means of worksheets, maps, and non-parametric statistics. Results show that Gravimetric Centers (obtained by the use of the calculus spatial means) of AIDS in Brazil are situated within a triangle the sides of which are formed lines joining the three main metropolitan areas of the wealthiest region of Brazil--the southeast, i.e. São Paulo, Rio de Janeiro and Belo Horizonte. These especially S. Paulo, function as points of attraction for these Gravimetric Centers (GCs) towards the south as compared with the GCs of the general population calculated ia accordance with data from the 1980 and 1991 censuses. It is possible to observe a displacement of the GCs toward the northwest over this period in accordance with the migration patterns of the Brazilian population in general, though with a dynamic of its own. These changes in the geographical, socio-demographic and transmission group patterns show the complex nature of the epidemic in Brazil and pose additional difficulties for the development of prevention strategies.
